carrier for the above-mentioned parts, which is flawless Alignment and proper seating of these parts is guaranteed.

It should be noted that the slide carrier described below for both the guide heads and is of the same training for the blow heads. For this reason, the description is based on the representations von Pig "2" * 5 on the application of the device to the guiding heads 21, 22 and 23, which are shown in Fig.l in the preform device. It should be emphasized that this description can be applied in the same way to the blow heads. For these reasons, Fig.l the same reference numerals have been used for the same parts, the parts of the slide carrier serving for the blow heads with are marked with the suffix A "

The slide carrier has a carrier 40 arranged laterally on a bearing hub 41. The bearing hub 41 is connected by a pin 42 to the vertical shaft 43 of a pressure medium-operated motor 44 which is fastened below the machine table 11 (see FIG. 1). The motor 44 is provided with conventional cam guides (not shown) which are connected to the perpendicularly arranged piston rod and shaft 43 are in connection and allow the shaft 43 a pivoting movement during part of the displacement process effected by the motor 44 in the vertical direction. Thus, when the motor 44 is actuated to raise or lower the vertical direction % u , the shaft 43 is simultaneously pivoted and moves the carrier 40 from a raised, out of range position to a lowered position above or above the distance 13 | 14 and 15, in which he places the guide heads on them *

As shown in Figures 3-5, the outer Section of the carrier «40 has a plate 45 with three sockets in
